To go online in Pokémon X/Y and OR/AS, you have to make some changes to your save file to go online unfortunately. This is quick and easy to do though, requiring just a few steps.
Thanks @piplupness for assisting with this!
Note: As a reminder, Pokémon X/Y and OR/AS are currently available for beta testers only. If you’d like to learn about beta testing, see the Donation Subscription FAQ for more information.
Also, make sure you have your 3DS friend code whitelisted for beta servers before connecting online as you’ll get error code 002-0110 otherwise.
You do NOT need to follow this guide if you connected to online servers in these Pokémon games on Nintendo Network servers in the past.
might add more screenshots later if I can be bothered
Prerequisites for this guide
- Checkpoint needs to be installed on your 3DS (you may have already done this when you first homebrewed your console)
- A Windows computer with PKHex downloaded GitHub
Connecting online
To get started, open the Checkpoint app on your Nintendo 3DS console and look for the game you want to connect online with (if you have the game on cartridge, make sure that the cartridge is inserted into your console).
Once you’ve found it, make a backup and choose a name for it (choose something memorable).
After that, exit Checkpoint and turn off your 3DS. Insert your SD card into your computer and open PKHex. When inside PKHex, press File > Open > Find your 3DS SD card > Checkpoint > Saves > Find the save you wish to edit.
Then, press SAV (this is found where you can see your party and box Pokémon) > Game Sync ID. You need to edit this to any number you want (it can’t be left on 0 though).
Once you’ve done that, press File > Export SAV and save into the same folder where your initial save file is in Checkpoint. I’d recommend using a different name so you still have the backup you made beforehand.
Now, just insert your SD card back into your 3DS and open up Checkpoint. Find the game which you’ve just edited the save file for and restore your edited save.
You should now be able to successfully connect online in Pokémon X/Y and OR/AS!
